Liverpool boss Jurgen Klopp admits they are set to take part in their strongest Champions League group since his arrival at the club.
The Reds are facing off against AC Milan, Atletico Madrid, and Porto, with only two teams set to advance to the knockout rounds.
Despite winning the competition a few years ago, the Reds know they face a real challenge to make the last 16 this term.
"This is the strongest group we have had since I've been at Liverpool, no doubt about that," said Klopp.
"In 2013 at Borussia Dortmund, we had a real "Champions League" group as well. We had Manchester City, Real Madrid and Ajax — a proper group! People said, "How will we get through?"
"What does it do for the competition? It kicks out two really good teams, it will deliver one really strong team into the Europa League, that's for sure! I never understand when people talk about changes to the Champions League.
"I like it how it is, and this group obviously shows that there are no games where people think, "Do I really want to watch that?" This group will be exciting from the first second to the last second. Nothing will be decided early. That keeps us on our toes."
